During my artist residency at Stanford University, a conversation about health implications due to pollution caught my attention. Some of the most severely polluted sites, co-called Superfund sites, are located in Santa Clara County, widely known as Silicon Valley. TCE was stored underground, and containers started leaking, polluting the ground water for decades to come. I visited the locations: light industrial buildings, campuses of tech companies, parking lots, sports grounds. The only visible sign of ongoing monitoring of the levels of TCE were these lids on the street. Watch this space – my next project will explore the notion of responsibility & contamination.
